Abstract (en)
[origin: EP1578005A2] A motor comprising a stator (136), a rotor (142), and a plurality of blades (154). The stator comprises a stator base (102) with an opening, a first magnetic structure (134) disposed at a bottom of the opening, a magnetic pole disposed on the stator base, and a second magnetic structure (138) disposed at a top of the magnetic pole. The rotor, coupled to the stator, comprises a hub (128), a shaft (144), a third magnetic structure (150) disposed at the hub and encircled one en of the shaft and corresponded to the first magnetic structure, and a fourth magnetic structure (140) disposed at the hub without contacting the second magnetic structure. The blades encircle the rotor. The first and third magnetic structures attract the second and the fourth magnetic structures, respectively.
